### 3.2 Use OpenSSL to Generate a Certificate

Use one of the following methods to generate a certificate using `openssl`:

* 3.2.1 [Generate a private key with ECDSA](#generate-private-key-with-ecdsa)
* 3.2.2 [Generate a private key with RSA](#generate-private-key-with-rsa)
* 3.2.3 [Generate a self-signed certificate](#generate-a-self-signed-certificate)

#### 3.2.1 Generate a private key with ECDSA

Ahora, desde una **perspectiva de desarrollador**, aquí hay varias cosas a tener en cuenta al pensar en HTTPS:

* Para HTTPS, **el servidor** necesita **tener "certificados"** generados por un **tercero**.
    * Esos certificados en realidad son **adquiridos** del tercero, no "generados".
* Los certificados tienen una **vida útil**.
    * Ellos **expiran**.
    * Y luego necesitan ser **renovados**, **adquiridos nuevamente** del tercero.
